Advice please. Anyone driven to northern Italy?

Thinking of taking my 458S in the summer thru northern france, switzerland and then around northern italy - the lakes, verona, bologna, portofino - and back. Some mates have said it sounds way better than reality - poor roads, summer hassle. Has anyone done a similar trip in a similar machine? Would be great to know if your experience was different or same above. Many thanks.

Thanks everyone. Really very useful advice, and some homework to be done evaluating options
Last question, thinking last 2 weeks of July.......from above I presume this just about works from a holiday traffic nightmare pov? Cheers.
